TYPE-WRITING MACHINE.

, SPECIFIGATION forming part of Letters Patent No. 567,937, dated September 15, 1896. Application filed July 12, 1892. Renewed January 18, 1896. Serial No. 576,046. (No model.)

To all whom it may concern.-

Be it known that we, IVILLIAM M. BLACK- STOCK, residing at Shadeland, in the county of Tippecanoe and State of Indiana, and JOHN OONLEY, residing at Chicago, in the county of Cook and State of Illinois, citizens of the United States, have invented certain new and useful Improvements in Type-W'riters, of which the following is a full, clear, and exact specification.

Our invention relates more particularly to that class of typewriters designed for travelin g over and writing upon the pages of open books, or other fiat surfaces, which cannot be conveniently fed through or inserted in the ordinary machine. A typewriter of this class is shown and described in our application for United States Letters Patent, Serial No.

398,188,1iled July 1, 1891, and also in United States Letters Patent to Elliott, No. 440,307,

granted November 11, 1890, to which reference may be had for a better understanding of any features that. are common to our present case and such prior devices.

Our present invention is designed as an improvement on said prior machines; and the improvements relate more particularly to the means for shifting the type-bars from upper to lower case, to the means for feed.

ing and supporting the carriage, and to the means for feeding the inking-ribbon. Our improvements also relate to certain other features of minor importance hereinafter described.

3 5 One of the important objects of ourinvention is to provide improved means for shifting the f ulcrums or pivotal points of the typebars whereby the change of the type from lower to upper case is effected.

Another important object of our invention is to provide the carriage with a shif table way or track and to balance the carriage thereon in such a manner that the way or track may be shifted together with the carriage for Ulla 5 covering or disclosing the Writing-surface, but Withoutdestroying the equilibrium of the carriage.

\Vith these ends in view our-invention construction, combination, and arrangement of parts by which the said objects and certain certain portions of the frame, the. ,being shown in section 011 the line 2 2, Fig. 1. Fig. 3 is an end elevation of the same, looking from the left, portions of the frame, the, being shown in section on the line 3 3, Fig. 1. Fig. 4: is a vertical transverse section taken on the line 4 4, Fig. 1. Fig. 5 is a detail front view of the carriage and a portion of its supporting way or track, aportion of the frame being shown in section. on the line 5 5, Fig. 1.. Fig. 5 is a detail sectional view hereinafter described. Fig. (3 is a detail view hereinafter described.

Like signs of reference indicate like parts throughout the several views. 5 In carrying out our invention we employ parallel rack-bars l, which rest upon the book yor writing-surface and serve as a support or track over which the base-frame 2, carrying the type-Writer proper, may be caused to travel by means of pinions 3, mounted in the cross-bar 2 and provided with suitable'opcrating-levers 4 for producing the desired space between the lines, all of which may be of the usual or of any suitable construction.

Mounted upon the rigid portion of the movable base-frame 2, preferably upon the outer ends of extensions 5, are two standards or uprights 6, to the upper ends of which are respectivelypivoted two crank-arms 7. The free ends of these cranloarms 7 are connected together by a rail or rod 8, which serves as a track or way for, the support and guidance of the type or printing carriage, the ends of the crank-arms 7 eing provided with jour- 5 nal-bearings 9, in i'hich the ends of the rail 8 are journaled. T e carriage is supported on this rail 8 by meaps of rollers or antifric tion-wheels 10, whose peripheries are provided with V-shaped or beveled edge grooves, which fit the correspondingly-beveled edge 8 on the upper side of the rail. Thus it will be seen that when it is desired to inspect the writing or remove the carriage from the writing-surface for any other purpose the crankarms 7 may be turned backward, carrying the carriage upward and backward with them, but without destroying the equilibrium of the latter, as it is balanced on the rail 8, and such bar is journaled in the arms 7.

In order that the carriage may be held at the proper distance from the writing-surface, the standards (5 are provided at or near their upper ends with flanges or extensions 11, arranged under the arms 7, and upon which said arms come to rest. If desired, each of the arms 7 may be provided with an adj ustable stop in the form of a set-screw 12, passing through a portion of the arm and adapted to impinge the flanges 11 for holding the free ends of the arms at the proper elevation.

In order to overcome a great portion of the weight of the carriage and render the same easier of manipulation, we provide the arms 7 with suitable counterbalances. These may consist of weights 13, secured in any suitable manner to the rear ends of the arms. As shown in the drawings, the standards 6 are provided with journal-bearings 6, through which short shafts or pins lat pass, which are secured at their inner and outer ends, respectively, to the arms 7 and weights 13. These details of construction, however, are immaterial, and it is of course seen that ordinary springs might be substituted for the weights.

The backward movement of the arms 7 may be arrested, if desired, by means of flanges or projections 15, formed on the standard 6 an d being similarto the flanges 11, the weights 13 being mounted to one side of the flanges 15,

so as to avoid striking the same.

The grooved wheels are journaled in suitable brackets or hangers 16, which surround and fit the under side of the rail or way 8, so as to prevent lost motion between such rail and the wheels, the hangers being provided with notches or recesses 17 for the passage of the teeth of the rack 18, formed on the under side of the rail, as usual. These hangers 16 are formed upon or otherwise secured to uprights or standards 19, to the lower ends of which the base-plate or bottom 20 of the carriage is secured. The disposition of the hang ers 16 is such that they will be directly over the center of gravity of the carriage and all parts supported thereon, so that the carriage will be equally balanced and will maintain a position parallel to the paper or writingsurface without the aid of additional supports. In order, however, that the pressure brought to bear upon the type-keys may not depress the front or forward side of the carriage or produce undue oscillation of the carriage upon its track or way, we provide such forward edge of the carriage with a support 21, which may consist of a plain flat flange formed along the inner edge of the bar 2 and projecting under the outer or forward edge of the plate 20, such plate, if desired, being provided with antifrictionrollers 22 to lessen the friction between it and the flange.

Mounted in suitable bearings or guides 23, preferably formed on the standards 19, are two vertically-reciprocating rods or guidestems 24, whose lower ends are secured, re spectively, to the sides of a plate 25, upon which the type-bars and key-levers are supported and fulcrumed.

The plate 25 is provided with a circular edge 26, as usual, around which the fulcrums 27 of the type-bars 28 are secured in any suitable manner, and such plate is also provided at or near its forward edge with a flange or ridge 29, which serves as a fulcrum for the key-levers 30. The key-levers 30 maybe secured to this flange 29 in any convenient way, but we preferably provide such flange with slits or notches 31, in which the key-levers are inserted, the levers themselves being provided with notches 32,which receive the flange 29 and thus prevent their endwise or longitudinal movement, their inner ends being connected to the typebars by a pin-and-slot connection 33, or by any other suitable or well-known means, and both the key-levers and type-bars being returned to their retracted or normal position by means of suitable springs 34, whose upper ends pass through perforations in the key-levers, while their lower ends 36 are seated in longitudinal perforations formed in the base of the flange 29. The type-bars 28, two of which only are shown in the drawings, are each provided, as usual, with two characters or types 37 38. The inner types or characters 38 are centered to strike the ribbon 39, which runs under the plate 20 at the same point, and the faces of the characters on each type-bar are set at such an angle that but one character on each bar can come in contact with the paper at the same time.

Thus it will be seen from Fig. 6 that when the fulcrum-plate 25 is in its lower position the inner characters 38 only will come in contact with the writing-surface; but should this plate be elevated, as shown in dotted lines, carrying the fulcrum of the type-bar upward to a point immediately over the position it occupies when lowered, thus placing it far ther from the paper or writing-surface, it will be seen that the forward character or type, 37, will be brought against the paper, while the other character, 38, will be carried upward and held aloof therefrom until the fulcrum or supporting-plate 25 is again lowcred. This upward movement of the plate 25 is so proportioned with relation to the distance between the characters 37 38 that the character 37, when the plate is raised, will I against the writing-surface.

As a means of imparting an upward movement to the type-supporting plate 25, we provide the rods 24 with lugs or projections 39,

' having antifriction-rollers 40, under which engage crank-arms 41, secured to a shaft 42, journaled in suitable projections 43, formed on or secured to the uprights 19. The upper edges of the arms 41 may be rounded or so formed as to readily elevate the bars 24 when an upward movement is imparted to such arms, and the shaft 42 is rigidly secured to both arms, so that the movement of one will be conveyed to the other without the necessity of applying the power to both directly. One of the arms 41 is attached or pivoted at 44 to an upwardly-projecting link 45, whose lower end is pivoted to the short arm of the shifting-lever 46, pivoted in any suitable manner to the base-plate 20. Thus by applying pressure to the key 47 of such shifting-lever both arms 41 will be caused to engage under the rollers 40 and elevate the plate 25 bodily, with the keys and type-levers thereon, to the position shown in dotted lines in Fig. 6, and it will there remain until the pressure on the key 47 is released, whereupon the parts will return to their normal position through the influence of gravity.- By this arrangement the fulcrum plate or support is elevated without changingits plane with reference to the horizontal; that is to say, if the plate is normally horizontal it will remain so throughout its movement, and hence the movement of the fulcrums will be uniform.

Mounted upon the forward edge of the plate is a crank-shaft 48, provided at each end, if desired, with ordinary cone or other suitable bearings 49. This crank-shaft 48 is provided with two inwardly-pro j ecting cran karms 50 51, which are rigidly attached thereto and carry at their inner ends a spacing bar 52.

The crank-arm 51 is provided with an extension 53, to which is pivoted the lower end of a link 54, whose upper end is pivoted to the end of a crankarm 55, suitablysecured to a rocker-shaft 56. This rocker-shaft 56 is journaled in any suitable bearings 57 on the standards 19 and carries the spacing-dog, which engages with the rack 18 on the under side of the-rail or track 8. The spacing-bar 52 is arranged across the machine under the type-levers 30, in a position to be impinged by such levers when the latter are depressed in the act of producing impressions or printin g on the writing-surface, and thus it will be seen that at each depression of the type-levers or of any one of them the spacing-bar will force the crank-arm 51 downward against the influence of the spring 58, whose'duty is to hold the spacing-bar normally elevated, and

will consequently rock the shaft 56 and cause the spacing-dog to release the rack 18 and thereby permit the feeding-spring hereinafter described to feed the carriage forward one space.

When the plate is elevated, the keylevers will of course be too far above the spacing-bar 5 2 to touch said bar when depressed, and in order that the movement of the keys may be imparted to the spacing-dog, through the connections already described,

when the plate 25 is in its upper position, we

provide a second spacing-bar 59.. The first spacing-bar 52 is permanently or immovably attached to the arms 51, Fig. 1, but the second spacing-bar 59 is capable of lateral or longitudinal adjustment with relation to the bar 52, and it is adapted to be shifted with relation to such bar automatically with the movement of the rising-and-falling plate 25. In order to accomplish this automatic movement of the bar 59, Fig. 5, the end of the latter is provided with an extension 60, in which is formed a cam-groove 61, through which passes the outer end of the shiftinglever 46.

The bars 52 59 are provided with vertical slots 62, in which the key-levers work, and which serve as guides for such levers and prevent'lateral play or. vibration thereof. As shown in Fig. 5, these slots 62 are coincident when the plate 25 is in its lower position,- and they arealso of equal depth in bothof the spacingbars. The extent of the slots in the bar 52 is such that the key-levers will strike or come to rest-on such bar in time to shift the feeding-dog to one side before the types strike the printing-surface, and the upper edge of the bar 59 is located at. such height as to be struck by the levers in time to shift the feeding-dog to one side before the types strike the printing-surface when the plate 25 is in its elevated position.

The formation of the cam-groove 61 is such that when this shifting-lever 46 is depressed the spacing-bar 59 is moved to one side, causing the slots in the two bars to become noncoincident and ranging the upper edge of the bar 59 in a position to be struck by the keylevers beforereaching the lower ends of the slots in the bar 52, thus causing the spacingdog to release the carriage when the keys are depressed while the plate 25 is in its elevated position. The upper portion of the camgroove 61 is such that when the shifting-lever 46 returns to its elevated position the shiftable spacing-bar 59 will be returned to its normal position with the slots therein coincident with the slots in the bar 52.

The bar 59 may be held in position on thearms 50 51 in any convenient manner. As

shown in the drawings, this bar 59 is provided at its lower edges with a number of longitudinally arranged slots 63, through which pass headed studs 64, secured to the fixed bar 52, thus holding the bar 59 upright ICC against the side of the bar 52, with capability of adjustment as described.

Preferably at the opposite side of the machine to the shifting-lever 4G is arranged the spacing-key 65, mounted upon the end of a suitable lever 66,as usual, which is fulcrumed at 67 to the base-plate 20 and pivoted at 68 to the extension 53 of the crank-arm 51, thus rendering it possible to feed the carriage forward without manipulating the type-keys, as will be understood.

The feeding-dog above referred to preferably consists of a collar 69, havinga set-screw 70, by means of which the same may be adj ustably secured to the rocker-shaft 56. As shown more clearly in Fig. 5, the upper side of the collar 69 is provided with a box 71, through which passes a pin 72, having a large and small end, as shown, and arranged on the small end of this pin, behind a shoulder 73, is a suitable spring 74, which normally imparts to the pin a tendency to move toward the feeding-spring 80. Projecting above the box 71, and being rigidly secured to or formed upon the collar 69, is a dog 75, having a number of teeth complementary in shape to the spaces between the teeth of the rack 18, and adj ustably secured to the face of the dog is a second dog 76, provided with a number of teeth, and being, if desired, identically like the dog 75, excepting that it is capable of slight longitudinal movement independently of the collar 69.

The dog 76 may be provided with longitudinal slots 77, through which pass headed studs or screws 78, fixed in the dog 75 or some other fixed part of the collar 7 O, as a means for adjustably holding such dog 76 in position. The dog 7 6 is provided at its ends with downwardly-projecting fingers or lugs 79 7 9, respectively, which engage with the ends of the pin 72, whereby the movement of such pin beyond the ends of the box 71 will be imparted to the dog, the pin being slightly greater in length than such box. Thus it will be seen that when the rocker-shaft 56 is rocked in one direction the teeth of the dog 7 (3 will be disengaged from the rack 18, and consequently the spring 74 will shift the dog 76 a short distance forward or toward the feeding-spring 80, this distance of course being equal to the distance between the teeth of the rack 18. WVhen in this position, the dog 57 will of course be in engagement with the rack 18 and hold the carriage against movement, but when the pressure on the key is released, permitting the spring 58 to rock the shaft 56 and force the teeth of the dog 76 between the teeth of the rack 18, the feedingspring 80, by virtue of its preponderance of power over the spring 74, will draw the carriage forward against the inertia of such spring 74 until the end of the box 71 strikes the depending lug 79, thus shifting the carriage one space, or the distance required between two letters of a word.

The feeding-spring 80 above referred to is coiled within a box or barrel 81, provided with a clamp 82 or other suitable device, by means of which it may be secured to the rail or track 8. The barrel 81 is preferably pivoted or journaled on a depending portion of the clamp 82, and one end of the barrel is provided with a drum 83, around which is wound a cord or cable 84, connected to a lug 85 on one of the standards 19, or to any other suitable and convenient portion of the earriage. The drum 83 is preferably of spiral form, as shown in Fig. 1, in order that the tension of the spring 80, as exerted on the carriage, will be uniform throughout the travel of the carriage, as will be understood.

With a carriage con strueted and arranged, as described, on the journaled rail or way 8, it will be understood that when the carriage is thrown backward from over the writingsurface its weight will hold its base '20 substantially parallel with the writing-surface, the standards 19 of course remaining vertical at all times, and as the rail cannot turn independently of the grooved supporting-rollers the position of the rail cannot change with relation to the spacing or feeding dog, which will remain normally in line with the rack 18. So also will the feed-spring mechanism maintain an unchz iging position with relation to the carriage.

Mounted on suitable journals 86,preferably projecting from the standards 19, are the ribbon drums or spools 87, upon which is wound the ribbon 39, passing under suitable antifriction-rollers 89, mounted in the edges of the plate 29. Each of these spools is provided with a pulley 90, around each of which passes a belt 91. The two laps or folds of each of the belts 91 are guided upward over a pair of idlers 92, journaled in projections 93, formed, if desired, on the rear sides of the standards 19, and from the idlers 92 each of the belts 91 passes around a pulley 94, having frictional connection with the ends of the rocker-shaft 56. This frictional connection between the rocker-shaft 56 and the pulleys 94 may consist of a spring-washer 95, bearing at its pe rimeter or edge upon the face of the pulley 94, and being held in place by means of a set or tension screw 96, whose end passes through such washer 95 and is threaded in the reduced end of the shaft 50.

Each of the pulleys 94 is provided on one side with ratchet-teeth 97,with which engages a pawl 98, pivotally fixed to the standard 19 or other suitable portion of the carriage. The arrangement of the teeth 97 and pawl 98 is such that the pulleys 94 are free to rotate with the shaft 50 in one direction, but when such shaft returns in the opposite direction the pawls 98 will engage the teeth 97 and overcome the frictional resistance of the springwashers 95, holding the pulleys 94 against a retrograde movement while the shaft 56 returns. This step-by-step rotation of the pulleys 94. will of course be imparted, through the-intermediary of the belts 91, to the spools 87, and consequently to the ribbon itself.

In order that both of the feedin g-dogs 7 5 7 6 may be simultaneouslydisengaged from the rack 18, we provide a spring-key 99, upon which is mounted a stop 100, which latter is normally held over the crank-arm 55, so as to prevent the spring 58 from forcing such arm upward sufficiently far to disengage both feeding-dogs from the rack 18, but when such stop 100 is withdrawn the arm will be free to move upward under the influence of the spring 58 and both dogs will be consequently thrown to the rear of the rack 18, and the carriage may be quickly and conveniently adjusted to any desired point throughout the alinement. The crank-arm 55 is provided with a key or button 55 for convenience in depressing such arm when it is desired to force it below the stop 100 and causethe dogs to again engage the rack 18, the upper side of the stop 100 being beveled to permit the arm 55 to readily pass it when forced downward. One of the standards 19, or any other desired portion of the carriage, may be provided with a rigid thumb-piece 101, to which the spring-key 99 is secured, and which serves as a brace or handle for the thumbin releasing the stop 100 and forcing the carriage to the desired adjustment.

Having thus described our invention, what we claim as newtherein, and desire to secure by Letters Patent, is-
